What Does PC Error Mean on Samsung DW80R9950 Series?

Error PC on your Samsung DW80R9950 dishwasher indicates a zone wash function check failure. This is a self-diagnostic alert triggered by the control board to verify proper operation of the zone-specific cleaning functions. While you can attempt a reset, persistent PC errors require professional service as they can involve internal component failures. First, power cycle the dishwasher by unplugging it for 5 minutes. If the error returns after restarting, contact Samsung-certified repair. ## What Does PC Mean? PC is a diagnostic error code exclusive to Samsung dishwashers with zone wash technology, specifically indicating a malfunction verification cycle failure in the targeted cleaning system. The dishwasher’s main control board runs automatic checks on the zone wash components (upper spray arm, targeted nozzles, and pressure sensors) during startup. When any part of this system fails to respond within expected parameters, the PC code appears. Unlike generic errors, PC specifically relates to the advanced cleaning features in premium models like the DW80R9950 series. ## Possible Causes 1. Zone wash solenoid valve failure - The electrically controlled valve directing water to targeted spray zones loses pressure regulation capability 2. Upper spray arm obstruction - Food debris or hard water deposits block the rotating nozzles designed for zone-specific cleaning 3. Pressure sensor malfunction - The sensor monitoring water flow in zone wash mode provides incorrect readings to the control board 4. Control board communication error - The main PCB fails to receive confirmation signals from zone wash components 5. Water inlet valve defect - Restricted water flow prevents adequate pressure buildup for zone wash functions ## Troubleshooting Steps | Step | Action | Expected Result | |------|--------|------------------| | 1 | Power cycle the dishwasher by unplugging for 5+ minutes | Temporary reset of error code | | 2 | 2 error - See details page for troubleshooting | Arm rotates freely with visible nozzle openings | | 3 | Run diagnostic mode (press Delay Start + Soil Level simultaneously for 3 seconds) | Display shows component test sequence | | 4 | Perform factory reset (hold Heat Dry and High Temp for 5 seconds) | All error codes clear temporarily | | 5 | Test zone wash function separately | No PC code recurrence during targeted cycle | ## When to Call a Technician Contact Samsung-certified repair under these conditions:

  • PC error reappears immediately after completing all troubleshooting steps
  • Zone wash functions visibly underperform (weak spray patterns in targeted areas)
  • Diagnostic mode shows “F5E2” or “F5E3” secondary codes
  • You hear unusual grinding noises from the solenoid valve area
  • The dishwasher fails to complete any cycle once PC appears ## Frequently Asked Questions ### Can I use my Samsung dishwasher with PC error? Not recommended - continued use can damage the zone wash components. Basic cycles can work, but targeted cleaning functions will be impaired.

How much does PC error repair cost? Typical service costs range depending on whether the solenoid valve ($90 part) or control board ($220 part) requires replacement.

Can hard water cause PC errors? Yes - mineral buildup can block zone wash nozzles and strain solenoid valves. Monthly cleaning with citric acid helps prevent this. ### Is it safe to keep using my Samsung DW80R9950 Series with error PC? If error PC does not indicate an immediate safety hazard such as a gas leak, electrical short, or water flooding, you can continue limited use while monitoring the appliance. However, running the dishwasher with an active error code increases the risk of further damage. Address the underlying issue as soon as possible. For high-severity errors, disconnect the appliance and contact a qualified technician. ### How much does it cost to fix error PC on a Samsung DW80R9950 Series? Repair costs for error PC on the Samsung DW80R9950 Series dishwasher depend on the root cause. DIY fixes such as cleaning filters, resetting the unit, or reconnecting loose wires cost nothing beyond basic tools. If a component replacement is needed, parts and labor from a certified technician are the main expenses. Contact a Samsung-authorized service provider for an accurate estimate based on your specific situation. ### What does error code PC mean on a Samsung dishwasher?
